ROUNDING AND CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 630,338, dated August8, 1899. Application filed December 16, 1895. Serial No. 572,258. NInfidel-l concern.-

Be it known that We, ZACHARY T. FRENCH and WILLIAM C. MEYER, of Boston,county of Suffolk, State of Massachusetts,have invented an Improvementin Rounding and Channeling Machines, of which the following description,in connection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention relates to machines for rounding and channeling the solesof boots and shoes while upon the last, and has for'its object toprovide such a machine with a guid ing device which is freely movableduring the rounding and channeling operation to vary the position of theboot or shoe with relation to the rounding and channeling knives,wherebythe sole will be reduced to its finished size and the width of itsprojecting edge may be varied, producing what is' commonly called aScotch edge.

The invention consists, essentially, in the combination of rounding andchanneling knives, feeding mechanism comprising two members whichreceive between them the projecting edge of the sole, and a guidingdevice for the boot or shoe, which is freely movable toward and fromsaid rounding and channeling knives during the rounding and channelingoperation to vary the position of the work with relation to said knivesin order that the width of the projecting sole may be varied. Theguiding device may be made to enter and even bottom in the creasebetween the upper and welt, or it may be made to bear against the upperadjacent the crease; be arranged to act upon where the rounding is beingdone and will be made tapering or pointed or quite thin, so as to serveproperly as a work-gage or guiding device for the boot or shoe along theshank as well as around the fore part. The workgage or guiding device ismade to continuously engage the boot or shoe all around- 'i. e., allaroundthat portion which is to be rounded and channeled. The feedingmechanism may be made in many difierent ways, and for simplicity thefeeding mechanism is herein shown as consisting, essentially, of twomembers adapted to receive between them but in either case itwill drawntaut over the last the work opposite the projecting edge of the sole andwelt and to be operated to feed along the work. The rounding andchanneling tools may be of any usual construction.

Figure 1 shows in side elevation a rounding and channeling machineembodying this invention; Fig. 2, a detail of the support for the upperfeed-wheel and guide.

The mainframe Ais shaped to support the working parts and is mountedupon the stand B. The shaft 1) has its bearings in said frame and has atone end a gear b,which is engaged by a pinion 19 secured to a shortshaft carrying a belt-pulley b A pinion 19 (see dotted lines) is alsosecured to said shaft 12 and en gages an intermediate pinion 19 which inturn engages a pinion b secured to a shaft carrying the'lower member ofthe feeding mechanism, herein shown as a wheel.

0 represents a channel-knife which is attached to the support 0'.

The rounding-knife d is mounted upon a vibrating arm (1, operated by anysuitable mechanism. This knife rounds or trims the edge of the sole.

8 represents a guide, which is made more or less V-shaped, as desired,to enter the crease between the welt and upper or to bear against theupper drawn taut over the last. The particular form herein shown isadapted to enter the crease. This guide is herein shown as a wheelaxially mounted upon the arm (2, which is formed integral with orsecured to the arm e pivoted at c to the upper end of one arm of abell-crank lever 6 pivoted at e to the frame, the other arm of saidbell-crank lever being connected with'a treadle-rod c, which passes downthrough the frame to a treadle. (Not shown.) By depressing thetreadle-rod c the bell-crank lever will be turned on its pivot and thearm 8 moved longitudinally, thereby moving the guide e in and out withrelation to the channeling and rounding knives.

The guide eis located so asto act upon the boot or shoe directlyopposite where the rounding is being done and not one side or the otherof such point. This is particularly impor tant in order that the shapeof the sole shall correspond with the shape of the bottom of the last,except where purposely varied.

' holder f,

knives, whereby the width of the projecting been employed in combinationwith a chan- -more particularly upon the upper drawn taut over the last.

' will be'seen, I bers which act upon opposite sides of the sole,

In addition to the feed-wheel b", which forms I the lower member of thefeeding mechanism, another feed-wheel is provided for-the opposite sideof the sole, and this upper member of the feedingmechanism is hereinshown as formed on the under side of the guide ethat is to say, on theunder side of this guide teeth are formed-and the guide being setobliquely said teeth at the point of contact or engagement with the workoccupy substantially a horizontal position. This guide and feed-wheel isplaced in a suitable support or which is cut away at f to accommodatethe rounding-knife as the guide is moved in and out. The support orholderf is attached to the forward part of the arm 6 Bevel-teeth f areformed concentrically around the axis of the feed-wheel, which areengaged by a bevel-gear f secured to a shaft 1, having its bearings inthe main frame, and to said shaft a toothed gear f is secured, which isengaged by a toothed gear f on the shaft b, so that by such drivingmechanism the feed-wheel will be positively rotated.

The guide and feed-wheel are formed in one piece merely for the sake ofsimplicity.

The arm 6 is pivoted at a so that it may be raised to admit the work.For the purpose of raising this arm a vertical rod or link n isconnected to 1t, the lower end of which is connected to one end of abell-crank lever 01/, pivoted to the frame, the other arm of which has along extension in the form of a handle 12*, which may be operated whendesired to raise the arm 6 We are aware that a movable guide hasneling-knife for the purpose of so varying the location of the boot orshoe that the channel-slit may be cut more or less distant from the edgeof the sole; but we are not aware that such a guide has ever beenemployed in combination with rounding and channeling edge of the solemay be varied and the channel cut.

The guide herein shown; it will be seen,

acts continuously all around the boot or shoe-that is tosay, all aroundthat portion thereof which it is desired to trim the edge of the soleand cut the channel-and the extent that it enters the 'crease dependsentirely upon the shape that may be given to it. If the V-s-haped edgeof the guide isquite sharp, it will not only enter but bot-tomin thecrease, and if made quite blunt it will hear The sole which is thusrounded is reduced to its finished size and to a desired shape along itsshank portion as well as fore part.

The feeding mechanism herein shown, it

comprises, essentially, two membeing held pressed together to clamp thesole and operated by suitable mechanism to feedl along the work.

channeling knives and The arm e is normally held pressed'down by thespring m. (See dotted lines, Fig. 1.) Two adjustable limiting-stops 0 oare provided for limiting the forward and rearward movement of theguide.
